Public bikesharing—the shared use of a bicycle fleet by the public—is an innovative mobility strategy that has recently emerged in major North American cities. Bikesharing systems typically position bicycles throughout an urban environment, among a network of docking stations, for immediate access. This paper discusses the modal shift that results from individuals participating in four public bikesharing systems in North America. The authors conducted an online survey (n =10,661 total sample), between November 2011 and January 2012, with members of four major bikesharing organizations (...

Evaluating Public Transit Modal Shift Dynamics In Response to Bikesharing: A Tale of Two U.S. Cities

Public bikesharing—the shared use of a bicycle fleet—has recently emerged in major North American cities. Bikesharing has been found to decrease driving and increase bicycling. But shifts in public transit have been mixed. The authors evaluate survey data from two U.S. cities to explore who is shifting toward and away from public transit as a result of bikesharing. The authors explore this question by mapping geocoded home and work locations of respondents within Washington DC and Minneapolis. Respondents were mapped by their modal shift toward or away from bus and rail transit. The...

Shared Mobility: A Sustainability & Technologies Workshop: Definitions, Industry Developments, and Early Understanding

Shared mobility - the shared use of a vehicle, bicycle, or other mode - enables users to gain short-term access to transportation modes on an “as-needed” basis. Shared mobility includes carsharing, bikesharing, ridesharing, and on-demand ride services. It can also include alternative transit services, such as paratransit, shuttles, and private transit services. Smartphone “apps” are available to aggregate options and optimize routes. New ways of transporting and delivering goods also have emerged with the potential to change the nature of the package and food delivery industry. Shared...

Mobility and the Sharing Economy: Potential to Overcome First- and Last-Mile Public Transit Connections

Chan, Nelson
2016

Shared mobility—the shared use of a motor vehicle, bicycle, or other mode—enables travelers to gain short-term access to transportation modes on an as-needed basis. The term “shared mobility” includes the modes of carsharing, personal vehicle sharing (peer-to-peer carsharing and fractional ownership), bikesharing, scooter sharing, traditional ridesharing, transportation network companies (or ridesourcing), and e-Hail (taxis). It can also include flexible transit services, including microtransit, which supplement fixed-route bus and rail services. Shared mobility has proliferated in global...

Shared mobility—the shared use of a vehicle, bicycle, or other mode—is an innovative transportation strategy that enables users to gain short-term access to transportation modes on an as-needed basis. The term shared mobility includes various forms of carsharing, bikesharing, ridesharing (carpooling and vanpooling), and on-demand ride services. It can also include alternative transit services, such as paratransit, shuttles, and private transit services (called microtransit), which can supplement fixed-route bus and rail services. With diverse options for mobility on the rise, smartphone...

Shared mobility—the shared use of a vehicle, bicycle, or other mode—is an innovative transportation strategy that enables users to gain short-term access to transportation modes on an “as-needed” basis. Shared mobility includes various forms of carsharing, bikesharing, ridesharing, on-demand ride services, and microtransit. Additionally, smartphone and mobile “apps” aggregate and optimize these mobility services and are critical to many shared mobility modes. Courier network services connect couriers using their personal vehicles or bicycles with freight and seek to disrupt the existing...

Bicycle use for commuting is being encouraged not only to address physical inactivity, but also vehicular congestion, air pollution and climate change. The current study aimed to ascertain the urban environmental correlates and determinants of bicycle use for commuting (bicycle commuting) among the working or studying population in Barcelona, Spain. Adults (n = 769; 52% females) recruited whilst commuting within Barcelona (Spain) responded to a comprehensive telephone survey concerning their travel behaviour. Based upon...

Overview of Shared Mobility

Cohen, Adam
2018

Shared mobility—the shared use of a vehicle, bicycle, or other travel mode—is an innovative transportation strategy that enables users to have short-term access to a transportation mode on an as-needed basis (1). Shared mobility includes various service models and transportation modes that meet diverse traveler needs. Shared mobility can include roundtrip services (vehicle, bicycle, or other travel mode is returned to its origin); one-way station-based services (vehicle, bicycle, or other mode is returned to a different designated station location); and one-way free-floating services (...
